--------------------------------------
Hi Eric,
Thanks again for your review! :) I'm afraid I'm still trying to understand your
suggestion. Lines 274-280 in hadoop-config.sh define HADOOP_HDFS_HOME relative
to HADOOP_PREFIX when it is not defined
{noformat}
# put hdfs in classpath if present
if [ "$HADOOP_HDFS_HOME" = "" ]; then
if [ -d "${HADOOP_PREFIX}/share/hadoop/hdfs" ]; then
HADOOP_HDFS_HOME=$HADOOP_PREFIX/share/hadoop/hdfs
#echo Found HDFS installed at $HADOOP_HDFS_HOME
fi
fi
{noformat}
So HADOOP_HDFS_HOME would get defined when it is not present. Wouldn't it be
better to define HADOOP_COMMON_HOME, HADOOP_HDFS_HOME and HADOOP_MAPRED_HOME
relative to HADOOP_PREFIX just once in hadoop-config, so that we don't have to
use if-else blocks everywhere else?

> hadoop-daemon.sh calls common/bin/hadoop for hdfs/bin/hdfs tasks and so
> common/bin/hadoop complains its deprecated for those uses.
